Specification of Letters Patent.

Patented Feb. 1, 1910.

Original application filed November 5, 1907, Serial No. 400,782. Divided and this application filed June 18, 1908. Serial No. 439,176.

To all whom it may concern:

Be it known that I, ANTHONY W. LosI-I- BOUGH, a citizen of the United States, residing at Detroit, Michigan, have invented certain new and useful Improvements in C01- lapsible Baby-Carriages, of which the following is a specification.

This invention relates to improvements in baby carriages.

It relates particularly to improvements in folding baby carriages, and is especially designed and adapted for use on the folding baby carriage shown in Letters Patent No. 866,145, issued September 17, 1907, to Otto Kurz; and I have shown my improvements embodied in such a structure, although they are applicable for use in Various other structures.

The main object of this invention is to provide in a folding baby carriage, an improved brace for the wheel and means for automatically securing the parts in their erected position.

Further objects, and objects relating to structural details, will definitely appear from'the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and point ed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the aceompanying drawing, forming a part of this specification, in which:

Figure l is a side elevation of a structure embodying the features of my invention, the wheels being removed and a portion of the handle broken away. Fig. 2 is a rear elevation, a portion of the handle being broken away. Fig. 3 is a side elevation of a structure embodying the features of my invention in its collapsed position, the wheel journals being broken away. Fig. 4c is an enlarged detail section taken on a line corresponding to line 4- 1 of Fig. 1, showing the detachable connection for the wheel braces to the wheel supports. Fig. 5 is a detail section showing the front support and brackets for the seat.

In the drawing, the sectional views are taken looking in the direction of the little arrows at the ends of the section lines, and similar numerals of reference refer to similar parts throughout the several views.

Referring to the drawing, 1 represents the running gear frame. The handle 2 is pivotally secured at the rear of the running gear frame by means of the pivots 3. On each of the side bars of the running gear frame are clip-like hangers 4. for the wheel supports 5. The wheel supports 5 are preferably formed of rods having downwardly-projecting wheel-carrying arms 6 with suitable journals, as 7, for the wheels. The wheel supports are pivotally supported on the hangers, so that they are free to swing therein to permit the wheels to be folded upon each other under the running gear frame. The wheel supports 5 are provided with offsets forming crank-like arms 8, the offsets being preferably inclined downwardly toward the rear, as clearly appears from the drawing.

A pair of levers 9 is mounted on the side bars of the running gear frame by means of the pivots 10, the pivots being located above the offsets or arms 8 of the wheel supports. The lower ends of the levers project downwardly below and preferably on the outside of the arms 8 of the wheel supports, as clearly appears from the drawing. On the lower ends of the levers are loops 11 arranged to engage the arms 8, so that-,when the levers are actuated, they serve to positively swing the wheel supports in and out to collapse or erect them. The levers 9 are preferably connected to the handle 2 to be actuated thereby, by links 12, the links being adapted to serve as side-bars for the seat 13. These parts described are substantially the same as the corresponding parts of the patent hereinbefore referred to.

The wheel supports are locked and braced by means of the braces 14, pivoted on the running gear frame at 15. These braces are preferably bail-like in form, their lower ends being connected by a suitable cross piece, as 16, whicl1 makes them more rigid and forms a very rigid brace for the wheel supports.

The arms 6 of the wheel supports are provided with fork-like clips 17, adapted to receive these braces when the Wheel supports are in their erected or extended position.

The upper ends of the braces 14 are preferably curved rearwardly and downwardly beyond the pivots 15 thereof, and are connected by the links 18 to the wheel support actuating levers 9. These links are so arranged that, when the braces let are in position to engage the wheel supports, the pivot connections 19 for the links to the braces are thrown below the pivots 15 for the braces to the running gear frame, so that they serve as an effective lock for the levers, thus securely locking the carriage in its open or erected position, as well as bracing the wheel supports. The cross piece 16 of the braces is, as will be observed, at the rear of the carriage, so that it may be engaged by the foot of the operator to release the braces or push them into engaging position, thus forming a very effective and convenientlyoperated device.

The seat 13 is preferably supported at its forward end on the bracket 20, the same being preferably mounted on the pivot 10 for the levers 9. Extending across the running gear frame, toward the rear thereof, is a cross piece 21. This cross piece is preferably formed of sheet metaland serves as a brace for the running gear frame. The springs 22 forthe seat 13 are preferably the spiral type and are mounted on the cross piece 21. This seat support is described in detail and claimed in my application filed concurrently herewith, the said application and this ap plication being divisional cases of my application for Letters Patent filed November 5, 1907, Serial No. 400,782.

lVhile I have illustrated the various parts in detail in the form preferred by me on account of the structural simplicity and convenience in manipulating the same, I am aware that my improvement is capable of being considerably varied in structural details without departing from my invention, and I desire to be understood as claiming the same specifically, as illustrated, as well as broadly;

Having, thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1.
